A Reversible Clearing Strategy Enables Robust Label‐Free Phase Imaging of Thick Tissues
Laser &Photonics Reviews, Volume 20, Issue 21, 6 November 2026.The principle of a reversible clearing strategy via glycerol and tartrazine solution (GTS) for robust whole‐slide label‐free phase imaging of thick tissue slices via high‐throughput Fourier ptychographic microscopy (FPM) and lensless digital holographic microscopy (LDHM). ABSTRACT Thick biological specimens impose strong scattering and attenuation that

Reconfigurable Light Field Generation With Hologram‐Enhanced Multicore Fibers
Nanophotonics, Volume 15, Issue 20, 27 October 2026.A novel metafiber platform enables reconfigurable generation of structured light patterns directly at the end of a multicore optical fiber. A 3D‐printed hologram maps individual fiber cores onto predefined image elements, allowing programmable pattern synthesis through selective core excitation.

Production and Evaluation of a Holographic Lens [PDF]
, 1978 This thesis is concerned with the production of high diffraction efficiency holographic lenses for laser machining. A holographic lens is a high efficiency, low absorption phase hologram which, in this application, is used to diffract an expanded ...

Nanophotonics, Volume 15, Issue 20, 27 October 2026.A multimode fiber probe collects far more of the near field than a single‐mode one, but scrambles the phase into speckle. Phase conjugation on a spatial light modulator restores the wavefront, concentrating the signal up to 165‐fold at a single detector pixel and recovering the full phase of propagating surface plasmon polaritons where conventional ...
